Represents an instrument that supports adding non-negative values. For example, you might call counter.Add(1) each time a request is processed to track the total number of requests. Most metric viewers display counters using a rate (requests/sec), by default, but can also display a cumulative total.

Methods

Add(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records the increment value of the measurement.
Add(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records the increment value of the measurement.
Add(T, KeyValuePair<String,Object>)	Records the increment value of the measurement.

Add(T, ReadOnlySpan<KeyValuePair<String,Object>>)	Records the increment value of the measurement.
Add(T, TagList)	Adds the increment value of the measurement.
Add(T)	Records the increment value of the measurement.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Publish()	Activates the instrument to start recording measurements and to allow listeners to start listening to such measurements. (Inherited from Instrument)
RecordMeasurement(T, KeyValuePair<String,Object>, KeyValuePair<String,Object>, KeyValuePair<String,Object>)	Records a measurement by notifying all MeterListener objects that are listening to this instrument. (Inherited from Instrument<T>)
